AUTOMATIC OILER.

SPECIFICATION forming part of Letters Patent No. 268,606, dated December 5, 1882.

Application filed October 16, 1882. (No model.) L

To all whom it may concern I Be it known that we, CHARLES BARBOUR and ALFRED BARBOUR, subjects of the Queen of Great Britain, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Oilers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art .to which it appertains to make and use the same, reference being had tothe accompanying drawing, and to the lettersand figures of reference marked thereon, which form a partof this specification.

Our invention relates to the lubrication of shaft or other bearings, en gine-cylinders, 850.,

- in which a revolving threaded shaft is the essential element-, and derives its rotary movement from the machinery to be oiled.

The objects of our improvement are'to provide an oiler or lu bricator which will work antomatically and only when the machinery is in motion, consequently only oiling the desired parts when needed or when the machine is operated. A further object is to bring the oil used back again into the oil-receptacle for reusing. We attain these objects by the mechanism illustrated in the accompanying drawing, in which the figure shows part plan and part sectional view.

A represents a vertical tube, which is open at its bottom end, and pierced with an opening at its top for the proper reception of the threaded spindle or shaft B. This spindle B has cut on one end a right-hand thread and on the other end a left-hand thread,as shown in the drawing. The lower end of the spindle may project beyond the lower end of the tube A, if desired, or vice versa. The tube A is provided with a casting or attachment, 0, by means of which it may be attached to the pillow-block or other partof the machine to be lubricated. The tube A has also a bracket, D, which carries on its outer-0r upper end a journal-bearin g. In this hearing runs the shaft F, which is provided with a pulley, G. The shaft or spindle F carries also a bevel-gear, H, which meshes with a corresponding bevel-gear, I, keyed to the upper end of the screw-threaded spindle B, and

l imparts motion thereto. K is the lubricatingpipe which leads to the parts to be oiled.

The operation of our improved device is as follows: The automatic oiler is attachedto any desired part of the machine to be oiledas the pillow-block-by means of the flange or castingC. Anoilreceptacleorvesselisplaced under the tube A, so that the end thereof will project below the surface of the lubricant. The pulley G is then connected by a pulleyband to a similar pulley attached to some moving shaft or spindle of the machinery or englue to be oiled. Upon the operation of the machine or engine the shaft F, through its band-connection on pulley G, will rotate, as also the bevel-gear H, which in turn will mesh with the bevel-gear I and rotate the vertical spindle B. In this automatic oiler the shaft B is arranged to revolve to the right, and it fits the tube A snugly,so that very little or no oil Will escape beyond the outer periphery of the thread. As the shaft continues to revolve the oil will be forced up into the tube till it reaches the outlet or lubricatingpipe K, which leads to the point or points to be lubricated. Should the supplybe greater than the demand, the oil will rise to the lower end of the upper left-hand thread in the top -of the case, which will tend to depress the oil. The automatic oiler, however, is so constructed that the oil will be fed only so fast as it canbe used, and

the thread in the upper part is chiefly instrumental in forcing the oil into the outlet-tube K, should it not flow freely. This construction and arrangement is such as to cause a continuous flow of oil upon any neck or hearing, and as the motion is entirely derived from the shaft which is being oiled, the flow of oil is regulated by the speed of theshaft. I r The oil-vessel or a connection therewith can be placed so as to receive all the oil which drips from the shaft lubricated effecting a considerable saving of oil by reusing the oil again. I

If desired, the upper thread of spindle B may be dispensed with or some other mechanical expedient substituted.

What we claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination, with a threaded spindle or shaft in a lubricator and its inclosing= tube,of mechanism,substantiallyasdescribed, shaft F, and pulley G, Substantially as set 'for automatically operating the lubricator, as

set forth.

2. In alubricator, a spindle or shaft having 5 oppositely-running threads at each end and a recess between them, in combination with its inclosing case and means, substantially as described, for operating the device.

3. The combination, in a lubricator, of inolosing-tube A, spindle B, bevel-gears I H, shaft F, and pulley Gr, substantially as described.

4. The combination, in a lubricator, of inclosing-tube A, spindle B, having oppositely- 1 running threads at each end, bevel-gears IE,

forth. 7 v

5. The'combination, in a lubricator, of tube A, having outlet-pipe K, leading to the point or points to be oiled, the threaded spindle B, bevel-gears I H, shaft F, and pulley G, substantially as and for the purpose herein specified.

In testimony whereof we afiix our signature; in presence of two witnesses.
